28 Ιουλ 2024 · The diaphysis is the central, elongated shaft of a long bone. It is a crucial component of the bone's structure, providing support and enabling movement. The diaphysis is characterized by its cylindrical shape, which allows it to efficiently bear weight and withstand stress.
A long bone has two main regions: the diaphysis and the epiphysis (Figure 6.3.1). The diaphysis is the hollow, tubular shaft that runs between the proximal and distal ends of the bone. Inside the diaphysis is the medullary cavity, which is filled with yellow bone marrow in an adult.
I. Describe the functions of the skeletal system and the five basic shapes of human bones. II. Describe the structure and histology of the skeletal system. III. Define and identify the following parts of a long bone: diaphysis, epiphysis, metaphysis, articular cartilage, periosteum, medullary cavity, and endosteum. IV.
Although bone cells compose a small amount of the bone volume, they are crucial to the function of bones. Four types of cells are found within bone tissue: osteoblasts, osteocytes, osteogenic cells, and osteoclasts ( Figure 6.11 ).
The diaphysis is the tubular shaft that runs between the proximal and distal ends of the bone. The hollow region in the diaphysis is called the medullary cavity, which is filled with yellow marrow. The walls of the diaphysis are composed of dense and hard compact bone.
1. Diaphysis. The central tubular shaft connects the two ends of the bone. Its walls are composed of dense and hard compact bone, forming an internal hollow region called the medullary cavity (as shown in the cross-section image above).
